Configuring Network Address Translation

About NAT

Network Address
Translation (NAT) enables private IP internetworks that use nonregistered IP
addresses to connect to the Internet. NAT operates on a router, usually
connecting two networks, and translates the private (not globally unique)
addresses in the internal network into legal addresses before packets are
forwarded onto another network. NAT can be configured to advertise only one
address for the entire network to the outside world. This ability provides
additional security by effectively hiding the entire internal network behind
that one address.

In
Cisco UCS Director, you can configure
NAT on the following Cisco network devices:

Cisco ASA 5500 Series
firewall

Cisco Adaptive Security Virtual Appliance (ASAv)
